What are the required steps to convert base 10 decimal system
number 10 101 000 949 to base 2 unsigned binary equivalent?

  • A number written in base ten, or a decimal system number, is a number written using the digits 0 through 9. A number written in base two, or a binary system number, is a number written using only the digits 0 and 1.

1. Divide the number repeatedly by 2:

Keep track of each remainder.

Stop when you get a quotient that is equal to zero.


  • division = quotient + remainder;
  • 10 101 000 949 ÷ 2 = 5 050 500 474 + 1;
  • 5 050 500 474 ÷ 2 = 2 525 250 237 + 0;
  • 2 525 250 237 ÷ 2 = 1 262 625 118 + 1;
  • 1 262 625 118 ÷ 2 = 631 312 559 + 0;
  • 631 312 559 ÷ 2 = 315 656 279 + 1;
  • 315 656 279 ÷ 2 = 157 828 139 + 1;
  • 157 828 139 ÷ 2 = 78 914 069 + 1;
  • 78 914 069 ÷ 2 = 39 457 034 + 1;
  • 39 457 034 ÷ 2 = 19 728 517 + 0;
  • 19 728 517 ÷ 2 = 9 864 258 + 1;
  • 9 864 258 ÷ 2 = 4 932 129 + 0;
  • 4 932 129 ÷ 2 = 2 466 064 + 1;
  • 2 466 064 ÷ 2 = 1 233 032 + 0;
  • 1 233 032 ÷ 2 = 616 516 + 0;
  • 616 516 ÷ 2 = 308 258 + 0;
  • 308 258 ÷ 2 = 154 129 + 0;
  • 154 129 ÷ 2 = 77 064 + 1;
  • 77 064 ÷ 2 = 38 532 + 0;
  • 38 532 ÷ 2 = 19 266 + 0;
  • 19 266 ÷ 2 = 9 633 + 0;
  • 9 633 ÷ 2 = 4 816 + 1;
  • 4 816 ÷ 2 = 2 408 + 0;
  • 2 408 ÷ 2 = 1 204 + 0;
  • 1 204 ÷ 2 = 602 + 0;
  • 602 ÷ 2 = 301 + 0;
  • 301 ÷ 2 = 150 + 1;
  • 150 ÷ 2 = 75 + 0;
  • 75 ÷ 2 = 37 + 1;
  • 37 ÷ 2 = 18 + 1;
  • 18 ÷ 2 = 9 + 0;
  • 9 ÷ 2 = 4 + 1;
  • 4 ÷ 2 = 2 + 0;
  • 2 ÷ 2 = 1 + 0;
  • 1 ÷ 2 = 0 + 1;

2. Construct the base 2 representation of the positive number:

Take all the remainders starting from the bottom of the list constructed above.

10 101 000 949(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

10 101 000 949 (base 10) = 10 0101 1010 0001 0001 0000 1010 1111 0101 (base 2)

Spaces were used to group digits: for binary, by 4, for decimal, by 3.

How to convert unsigned integer numbers (positive) from decimal system (base 10) to binary = simply convert from base 10 to base 2

Follow the steps below to convert a base ten unsigned integer number to base two:

  • 1. Divide repeatedly by 2 the positive integer number that has to be converted to binary, keeping track of each remainder, until we get a QUOTIENT that is equal to ZERO.
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above. Thus, the last remainder of the divisions becomes the first symbol (the leftmost) of the base two number, while the first remainder becomes the last symbol (the rightmost).

Example: convert the positive integer number 55 from decimal system (base ten) to binary code (base two):

  • 1. Divide repeatedly 55 by 2, keeping track of each remainder, until we get a quotient that is equal to zero:
    • division = quotient + remainder;
    • 55 ÷ 2 = 27 + 1;
    • 27 ÷ 2 = 13 + 1;
    • 13 ÷ 2 = 6 + 1;
    • 6 ÷ 2 = 3 + 0;
    • 3 ÷ 2 = 1 + 1;
    • 1 ÷ 2 = 0 + 1;
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above:
  • 55(10) = 11 0111(2)
  • Number 5510, positive integer (no sign), converted from decimal system (base 10) to unsigned binary (base 2) = 11 0111(2)
